Patent CA-2056355-A1 (CA)
Inventor: LAURENT GASCON
IPC: E04H15/20
Filed: 1991-11-27
Abstract: Cette invention est un abri, composé de deux parties distinctes, le toit et la base. Le toît est conçu d'après un principe selon lequel une structure tubulaire en tissu étanche,(gonflée fortement avec de l'air), peut en contraindre une autre (gonflée plus faiblement) à laquelle elle est assemblée, à prendre une forme oblongue qui devient la toiture de l'abri. L'idée générale est que la structure la plus forte, une charpente en forme de câdre, limite l'expansion sphérique de la plus faible, celle-ci étant composée de deux toiles superposées couvrant l'aire de ce câdre et étant assemblées à celui-ci sur son périmètre. La deuxième partie, la base de l'abri, est l'application d'un principe utilisé pour les ponts suspendus, ammené ici à supporter le toît gonflable de la façon suivante: A chacun des coins de l'abri, un pillier est installé, ce sont les pattes de l'abri sur lesquelles le toît est déposé. Entre ces pattes, des câbles sont lâchement tendus le long des arrêtes du toît, de telle façon qu'on puisse suspendre celui-ci à différents points de ce câble. Ces câbles permettent donc d'utiliser une pression moindre pour gonfler la charpente du toît, Pour pouvoir ainsi couvrir de plus grands espaces sans pôteaux de soutennement sur les côtés de l'abri.

Patent CA-2085847-A1 (CA)
Inventor: NOWAKOWSKI MICHAEL V
IPC: F41G7/00
Filed: 1992-12-18
Abstract: A system and method that uses differential computation of position relative to aglobal positioning system (GPS) coordinate system and the computation of an optimum weapon flight path to guide a weapon to a non-moving fixed or relocatable target. The system comprises an airborne platform that uses a navigation subsystem that utilizes the GPS satellite system to provide the coordinate system and a synthetic array radar (SAR) to locate desirable targets. Targeting is done prior to weapon launch, the weapon there-fore requires only a navigation subsystem that also utilizes the GPS satellite system to provide the same coordinate system that the platform used, a warhead and a propulsion system (for powered weapons only). This results in a very inexpensive weapon with a launch and leave (autonomous) capability. The computational procedure used in the platform uses several radar measurements spaced many degrees apart. The accuracy is increased if more measurements are made. The computational algorithm uses the radar measurements to determine the point in a plane where the target is thought to be and the optimum flight path through that point. The weapon is flown along the optimum flight path and the impact with the ground results in a very good CEP when a sufficientnumber of radar measurements are made. The present invention provides fully autono-mous, all-weather, high precision weapon delivery while achieving a relatively low cost. High precision weapon guidance is provided by the unique differential guidance technique (if a sufficiently accurate and stable navigation system is used).

Abstract: A B S T R A C T  A method and a device for measuring X-ray radiation from Cath-ode Picture Tube (CPT) are provided. An X-ray detector is located on the screen of CPT. Memory1 is used to store a true signal plus background and memory2 to store background. Signals from the detector are transfered to memory1 whenever the electron beam hits dots facing the sensitive area of the detector and to memory2 whenever the electron beam scans the screen outside the sensitive area. Light sensitive elements are used to determine the position of the electron beam on the inner surface of the screen. A dramatic improvement in the ratio of true signal to background is successfully achieved.

Abstract: A metal casting control device is provided for use in conjunction with a semi-continuous metal casting system.  The control device is an integral module containing a metal surface elevation sensing device, a valve actuator for positioning a metal distribution control valve, and electronic circuits associated with these mechanical components.  The control device module is adapted to be connected to an overhead metal distribution launder by a single quick-coupling for convenient and simple removal and replacement. Calibration of the control device is performed after installation by mounting a calibration target on the metal casting system and vertically adjusting the metal surface elevation sensing device until an integral calibration indicator positioned on the control device indicates that the proper vertical position has been attained.  The metal surface elevation sensing device is formed by a manually-adjustable sensor carriage and a sensor support which is mounted for automatic vertical movement relative to the sensor carriage.  An inductive proximity sensor is supported over a metal casting station by the sensor support.
